The effect of combined application of organic manure and chemical fertilizers on N use efficiency(NUE) in paddy fields and the environmental effects in Hang jiahu area were studied by field experiments and 15N isotopic tracer.The results showed that combined use of 150 kg/hm2 nitrogen and 3 000 kg/hm2 organic manure improved the yield of rice by 9.8%~17.7%.The N use efficiency was 47.9%
and 4.8% higher than that of chemical fertilizers only.While combination of 210 kg/hm2 nitrogen and 3 000 kg/hm2 organic m...
